Application filed January 11, 1915. Serial No. 1,527.

T0 all whom it may concern:

Be it known that I, AUGUST SUNDH, a citizen of the United States, residing in Hastings-upon-I-Iudson, in the county of IVestchester and State of New York, have invented a new and useful kImprovement in Gate-Hinges, of which the following is a specification.

My invention relates to gate hinge mechanism, and has for its principal objects the provision ofy a hinge which will center the gate and keep thesaine centered; also a hinge which will carry very heavy loads with the minimum of wear; a hinge which is vself lubricating at all times; a hinge in which the swing of the gate back and forth by central position after having been operated is reduced to a minimum, and a hinge in which the parts are well protected from the elements. I

vVith these and other objects in view, I have devised an apparatus which isv fully set forth in detail kin the accompanying drawings. Referring now to the drawings, Figure l is a sectional elevational view showing'my device applied to a gate and gatepostV with the parts in central position; Fig. 2 is a sectional plan view taken on the line a-a of Fig. l; Fig. 3 is a sectional plan view of part of Fig. l taken on line 5 5; Fig. t is a sectional plan view on the line d-CZ of Fig. l; Fig. 5 is a sectional plan view on the line e-e of Fig. l; Fig. 6 is a part sectional elevation view showing the position taken by the hinge when the gate is opened inv one direction; Fig. 7 shows in sectional elevation the hingev with gate opened in the opposite direction.

Referring to the drawings in detail, my hinge Acomprises two telescoping parts or cups, l and 2in this instance the part l, being attached to the gate, and part, 2, to the gate post, it being understood, however, that their location may be reversed. The

part, 1, has a lateral extension, 3, substantially rectangular in cross section, the outer face of which is concaved to fitnicely the face of the gate to which it is to be attached. 'Io secure the hinge to the gate, I have provided a clamp, 4, having its face concaved to fit the face of the gate. These clamping members are secured to the gate by means of bolts, 5, one on each side of theA face of the gate. I have. shown the part, 2, formed with an extension similar `the inside of the part, 2.

ring, 7.

to that on part, l, which extension is se cured to the gate post in the same way as the extension, 3, is secured to the gate. The inside of the part 2 is cylindrical in shape, nearly to the bottom, where the cylinder' is reduced in diameter, forming a shoulder, 6, on the inside ofthe cylinder, near the bottom. Resting on this shoulder, 6, is a ring, 7, slightly smaller in diameter than Formed on the bottoni of this ring is a downwardly extend ing projection, 8, a clearance being left betweenV the end of this extension and the bottom of the cylinder.

through the extension and through 'the Thisport is of a shape to permit a ball valve, l0, to be retained therein; This portion of the port extends up to about midway of the depth of the ring,

larged.

Formed on the inside of the cylinder, 2, and extending longitudinally of ity from about midway of its length to the shoulder,

n. Formedin this extension 1s a port, 9, which passes upV 'the rest of the port being very much en- 6, are ribs, l1, (see Fig. 4:), two in number,

set diametrically Vopposite each other.

Spaced at equal distances around the periphery of the cylinder 2, and on the inside, are cut four grooves, 12, for a purpose hereinafter pointed out; and spaced between two sets` of these grooves, 12,V and diametrically opposite each other are two more grooves, 13. All these grooves extend longitudinally of the cylinder from about midway the length of the cylinder to the shoulder 6. Mounted in the cylinder-,2, is a spindle, lat, fitted in Babbitt metal bearings, orsome other antifriction metal bearings, the, spindle itting rather loosely.

This spindle, 14, has cut therein very coarse threads, the lowerhalf of the spindle having a plurality of left hand threads and the upper half a plurality of right hand threads.

I have in practice found it very desirable to have a plurality of threads on the spindle in order to get suflicient bearing surface and at the same time have a sufficient depth of pitch. The antifriction metal bearings for the spindle is securely held inplace as will be explained more in detail later on. K

Formed on thel spindle la, at about its middle, is a collar, 16, the diameter of which is large enough to permit the "collar 25 l Y 16, and the top of the spindle does vnot quite touch the inside of the bottom of the k50 'y nection with the upper ballvalve.

. VThe method of assembling the hinge is as other.

to span a little more than the distance between the ribsv11. The length lofthe ribs 11, and the position of the collar, 16, on the spindle, 14, are such that when the end of the spindle rests on the ring, 7, vthe col.- lar, 16, will resten the top of the ribs, 11. The grooves, 1,3, are formed wedge shaped, that is smaller at the bottom than at the vtop, which prevents the babbitt from being pulled out of' the cylinder, The upper halff ofV the. spindle, 14, carries the upper cylinder, 1. This cylinder is slightly larger in diameter than the lower part, 2. Y Formedl withinthe cylinder, 1, is a cncentriccylinder, 17 having two grooves,

lftherein,y set diametrically.opposite each These grooves are wedge shaped,

' being larger at the bottom than at the' top, 'being so ormed to retain the antifriction VVmetal' bearing 19L in place, said bearingy ,bei

cylinder, 17. A Y v Y y Extending down through the center of the spindle Vis a small opening, 20, which 4 extends down until it meets an opening 21, v'let into the collar, 16 at right angles yto the opening, 20. This opening 21, is screwthrea'ded to receive a hollow plug 22, carrying a ball valve. 23. VFormed within this plugfis Aa4 shoulder 24 smaller in diameter than the diameter yof the ball', 23.`V Inv assembling this valve,"the ballis dropped intol '-therplug from the inner end and then the endV of the plug l,struck a slight blow `enough to'close the opening sufficiently to retain the ball within the plug. The shoulder, 24pre'- vents the ball escaping through the other end of the plug. The ball valve the lower part of vthe hinge is assembled in the same way. ln this case thejl'ower part of the ,f port, 9, being smaller in diameter than the ball, 10, the ball isfdroppedin to the port from the top andthen t top is partially closed the same as just pointed out in coni "foll'ows: The ring, 7, is provided with cut out portions, 12, four in number, located so as to register with' the openingsor grooves, 12, on the inner wall of the cylin.

der 2, when the ring is in place. I also provide cut out portions, 13', in the periphery of thev ring, which register with the lower portion of the grooves, 13, in the wall of the cylinder,r 2when the ring 'is in place. With of' the cylinder, 2, andl in the ring, 7, are

driven into the several openings just' mentioned'. Babbitt metal in a molten state is then poured into the opening vor space Varound the spindle completely filling the space and also filling the space between the threads'. The plugs, it shouldy be noted, are

not t0 be driven into the groovesv 18", but

only in the y grooves 12 andl cut out portions 12', registering therewith. The babbitt will thereforell' up the grooves 18 and'13 registering therewith.

It will' thus be seen that when the false spindle' is screwed out the Babbitt metal willY be left' inplace screw threaded to form a bearing for the true Vspindle 14.' The groovesV 13', and 13', will prevent the' babbitt from'being pulled out, beingfwedg'e shaped, and also hold the ring,

7, firmly in the one position; The Vbabbittr in the upper part of the hinge is putin much the same way', in this' case the wedge shaped grooves, 18, holding the babbitt from being pulled'V out; The plugs are then knocked out, leaving four grooves, 12, extending up the side ofthe babbitt on its outer periphery in the lower part of the hinge.. The cup`2 is then partially lled with lubricant, and the spindle, 14', screwed down into the ,lower bearing until it rests on the collar 7 at that time the colla-rv 16 will' resten the shoulder or ribs, 11. `The upper part of the hinge is then screwed down on to the spindle, 14, the

Yrelative 'lengths of all the parts being such that when the lowerl end of the cylinder 17 rests on the collar 16, there willl be a slight clearance between the upper part of the spindle, or upper end of the spindle, 14, and the inside of the bottom of the cylinder 17, anda slight clearance betweenl the top of the part 2' andl the bottom of the-partl.V A clearance is allowedl between the Vparts 17 and 2. Y

In operation, suppose vthe gate is opened as shown in' Fig. 6; in this case, the tendency of the 'spindle is to screw down into its bearing, but by reason of the collar 16 resting onthe ribs 11 it is held from moving longitudinally and the upper part of the hinge will' therefore travel up the Vupper y part of the spindle as shown in Fig. 6, at the same time the lubricant will' be drawn into the port 21 and will flow up through the opening 20, up into v'the space whichffwill then be present between the top of the spindle and the bottom of the cylinder 17. l/Vhen the gate is released it will return to its central position by its own weight, being heavy enough to travel'down'the threads of the spindle and at the same time by reason of the said threads returning to closed position. By reason of the ball valve 23 the oil which was in the chamber above the yupper end ofthe spindle cannot escape through the port, 21, and it will therefore be forced down through the threads of the spindle lubricating the threads of 'the spindle thoroughly. In addition to this forced lubrication, my arrangement has the advantage of slightly retarding the closure ofthe gate, which is a great advantage. When opening the gate in the opposite direction, the tendency of 'the upper part of the hinge is to screw down on to the spindle, but is prevented from so doing by reason of the cylinder' 17 contacting with the collar 16. Thek whole spindle will have to turn therefore and be drawn partially out of its bearing, that is its lower bearing. This will suck oil up through the port 9 into the chamber which will then be present at the bottom of the spindle. When the gate is released and closes the oil will be prevented from escaping through the porty 9 by reason of the ball l0 and it will therefore be forced up through the threads of the spindle, thoroughly` lubricating them. The retarding eifect of the oil will be prese ent in this instance as in the case of opening the gate in the opposite direction, as is obvious.

It will thus be seen that I have provided a very simple efiicient hinge, and one which will always be thoroughly lubricated. The fact that the gate is lifted bodily Veach time it swings past closed position is an excellent feature, as it, to a great extent, does away with the swinging back and forth of the gate under its own momentum as is the great trouble with hinges at present in use. In addition to that, I have the retarding effect of the oil to cut down the momentum of the gate in closing. I only leave a small space between the top of the part 2 and the inside of the part l, which together with the telescoping nature of the two parts quite ediciently keeps out dirt from the inside ofthe hinge.

It is to be understood that those skilled in the art may make various changes in the details of construction and arrangement of parts herein shown, without departing from the spirit and scope of my invention, desire therefore not to be limited to the precise construction shown.

What I claim, and desire to secure by Letters Patent of the United States is l. A gate hinge, comprising a stationary member and a manually operable member,
